If you're sure you should have gotten an invite, check your spam folder. Sometimes system-generated emails can fall through the cracks, no matter how awesome they may be.
Still couldn't find an invite? Well, the portal is currently available in a "closed beta" program, which means that unfortunately, not all of our customers have access to the service (yet). If you didn't receive an email invitation from us (or from someone on your team), you may need to wait a little bit :(.
If you would like to sign up for updates or to get access to the portal in future releases, please send an email to us at "firstname.lastname@example.org".
